A VPN and antivirus software are both commonly described as security tools, but they protect against different types of risks.
A VPN, or virtual private network, primarily creates an encrypted connection between your device and the VPN service. It can be useful for protecting the connection between your device and the VPN server, particularly when you’re using networks you don’t fully control.
Antivirus software, on the other hand, is designed primarily to detect, block, and remove malicious software such as viruses, spyware, ransomware, and other forms of malware.
Because they address different risks, a VPN isn’t a replacement for antivirus software, and antivirus software isn’t a replacement for a VPN.
VPN vs. Antivirus at a Glance
| Protection | VPN | Antivirus |
|---|---|---|
| Encrypts the VPN connection | Yes | No |
| Helps protect traffic on certain networks | Yes | No |
| Helps hide your IP address from websites | Generally | No |
| Detects malware on your device | No | Yes |
| Scans files for malicious software | No | Yes |
| Blocks certain malicious files | No | Yes |
| Helps detect ransomware | No | Often |
| Helps protect against malicious downloads | Some VPN products offer related features | Often |
| Protects against every phishing scam | No | No |
| Replaces security updates | No | No |
The exact capabilities vary by VPN and antivirus provider, so individual products should always be evaluated based on their actual features.
What Does a VPN Protect You From?
A VPN creates an encrypted connection between your device and a VPN server. This can provide an additional layer of privacy when you’re connected to the internet.
One common reason people use VPNs is to reduce the exposure of their internet traffic on networks they don’t control.
Public Wi-Fi
Public Wi-Fi is available in places such as airports, hotels, restaurants, and coffee shops.
Modern websites and apps commonly use encryption themselves, which means public Wi-Fi isn’t automatically unsafe. The FTC notes that most websites now use encryption and recommends looking for HTTPS when using a browser.
A VPN can provide another encrypted layer for traffic between your device and the VPN service.
However, a VPN should not be viewed as a guarantee that everything you do online is safe.
Your IP Address
A VPN can generally make websites see the VPN server’s IP address rather than your home or mobile connection’s IP address.
This can provide a degree of privacy and can make your approximate network location appear different.
However, changing your IP address does not make you anonymous.
Websites and online services can use other information to recognize or identify users, including accounts, cookies, browser characteristics, and information users voluntarily provide.
Network Privacy
A VPN can help protect traffic between your device and the VPN server from people on the same local network.
This can be particularly relevant when using networks you don’t manage yourself.
But the VPN provider becomes an important part of the connection. Your traffic is being routed through the VPN provider’s infrastructure, so it’s worth researching the provider’s privacy practices and policies before choosing a service.
What Does a VPN Not Protect You From?
This is one of the most important things to understand.
A VPN does not automatically:
- Remove malware from your device
- Stop every phishing attack
- Prevent you from downloading malicious software
- Make fraudulent websites legitimate
- Protect an account with a stolen password
- Guarantee anonymity
- Replace operating-system security updates
- Prevent every form of online tracking
For example, if you receive a phishing message and voluntarily enter your password on a fraudulent website, a VPN doesn’t necessarily prevent that information from being submitted to the scammer.
The FTC also warns that scammers can create websites that use encryption. HTTPS can protect the connection to a website, but it does not prove that the website itself is trustworthy.
What Does Antivirus Software Protect You From?
Antivirus software focuses on threats that can affect the device itself.
Malware is a broad term that includes viruses, spyware, ransomware, and other harmful software. The FTC recommends using reputable security software and keeping it updated because criminals continually develop new ways to distribute malware.
Depending on the product, antivirus software may provide:
- Real-time malware detection
- File scanning
- Download scanning
- Ransomware protection
- Spyware detection
- Malicious application detection
- Quarantine and removal
- Web or phishing protection
The exact feature set varies by provider.
What Happens If You Download Malware?
Imagine that you receive an email containing a malicious attachment.
A VPN doesn’t determine whether the attachment contains malware simply because your internet connection is encrypted.
Antivirus software, depending on its capabilities, may scan the file and detect malicious code or behavior.
This illustrates the basic difference:
VPN: protects aspects of the connection.
Antivirus: protects the device against malicious software.
They operate at different layers.
What About Phishing?
Phishing is another area where the distinction becomes important.
A phishing attack may attempt to convince you to:
- Click a malicious link
- Enter your password
- Provide payment information
- Download a harmful file
- Contact a fraudulent phone number
A VPN alone doesn’t generally determine whether a message is legitimate.
Some antivirus and security suites include web protection or anti-phishing features that can warn users about known malicious websites or links.
But even these tools aren’t perfect.
The FTC recommends being cautious with unexpected messages and links and warns that scammers often impersonate companies or organizations to obtain personal information.
VPN vs. Antivirus: Which Is More Important?
There isn’t a universal answer.
The two tools address different risks.
If you’re primarily concerned about malware infecting your computer or phone, antivirus or built-in device security is more directly relevant.
If you’re concerned about privacy and securing your internet connection on certain networks, a VPN may be useful.
If both concerns matter to you, using both can make sense.
But buying both doesn’t mean you’re protected from every online threat.
Do You Need Both?
For some people, using both a VPN and antivirus can provide complementary protection.
For example:
VPN
→ Encrypted VPN connection
→ Privacy on certain networks
→ Different apparent IP address
Antivirus
→ Malware detection
→ Malicious-file protection
→ Ransomware protection
→ Potential web/phishing protection
The combination addresses different areas of online security.
However, before buying either product, check what your device already provides.
Modern operating systems include built-in security features. For example, Windows includes Microsoft Defender Antivirus and Windows Firewall.
You may therefore already have some antivirus and firewall protection without purchasing a separate security suite.
What Should You Consider Before Buying a VPN?
If you’re considering a VPN, look at:
Encryption and connection security
Understand how the service protects the connection between your device and its VPN servers.
Privacy policy
Find out what information the provider collects and how it handles that information.
Server locations
If location options matter to you, check where the provider operates servers.
Supported devices
Check whether the service supports the computers, phones, tablets, or other devices you actually use.
Simultaneous connections
Some providers allow multiple devices to use one subscription, while others impose different limits.
Additional features
Some VPN services offer additional features such as malicious-site blocking, tracker blocking, or other privacy tools.
Don’t assume every VPN includes the same features.
What Should You Consider Before Buying Antivirus Software?
Look at:
Malware protection
What types of malware does the product detect and block?
Real-time protection
Does it continuously monitor activity?
Device compatibility
Does it support your operating system and devices?
Web protection
Does it include protection against malicious websites and phishing?
Ransomware protection
Does the product provide specific protection against ransomware?
Number of devices
Does the subscription cover one device or multiple devices?
Renewal price
What will you pay after the introductory period?
Additional features
Some security suites include VPNs, password managers, identity monitoring, parental controls, or other tools.
Only consider these valuable if they’re features you actually need.
Don’t Forget the Security Basics
Neither a VPN nor antivirus software replaces good security habits.
The FTC recommends keeping your operating system, browser, applications, and security software updated. It also recommends using strong passwords and multifactor authentication where available.
Other useful practices include:
- Keep important files backed up.
- Avoid unexpected links and attachments.
- Download software from trusted sources.
- Use multifactor authentication on important accounts.
- Don’t reuse passwords across important accounts.
- Secure your home Wi-Fi network.
- Keep your devices updated.
These measures work alongside security software rather than being replaced by it.
VPN or Antivirus: Which One Should You Get?
Consider a VPN if your primary goal is improving privacy and securing your internet connection in situations where that additional layer is useful.
Consider antivirus or security software if your primary concern is malware and protecting the device itself.
Consider both if you want complementary protection for your device and internet connection and the additional features justify the cost.
And before buying either, check your existing operating system and security settings. You may already have some of the protection you need.
Final Thoughts
A VPN and antivirus program aren’t competing versions of the same security product.
A VPN primarily focuses on the connection and network privacy, while antivirus software primarily focuses on malware and threats to the device.
Neither one provides complete protection on its own.
The best approach is to understand the risks you’re trying to reduce, check what protection you already have, and then compare products based on their actual features, limitations, supported devices, privacy practices, and long-term cost.
